It is a Dynamix 16:8:2 , made in England , and belongs to a friend of mine.
The PSU is missing, and we are wondering if anybody knows what is the voltages and wattage on the pictured XLR power connector.
I have been told this company later merged with Dynacord, this might help...
Thanks! 🙂

Look inside. YOu have four pins and the shell on the connector. Thatmeans there are likely three supplies and a common ground, with the shell just earth. or possibly four supplies and the shell is the ground return.
Inside, is the shell wired to the circuits? Or is the shell left unwired or just wired to the metal chassis?
I assume the mixer circuits are based on op amp ICs? If so, there will be positive adn negative something to run them. 15v is common, 12v less so in mixers. 17v is more and more common, but pushing the ICs if it gets out of spec much. In any case, +/-15v would probably work fine. It should be easy to determine which cinnector pins are wired to the + pins of hte ICs and which the negative.
A mixer like that probably has phantom power on the mic jacks, does it? Phantom should be +48v, however, some cheat and provide something lower like 12v. COnsidering the meter bridge across the top, that look like they might be illuminated? There will be some voltage for those lights, not to mention any LEDs on the panel. Those would not usually be running of the same voltage supply as the signal circuits for noise reasons.
+/-15v at maybe 2 or 3 amps.
